SPECIFICATION forming part of Letters Patent No. 754,571, dated March15, 1904.

Application filed Iuly 30, 1903- Serial No. 167,637. (No model.)

To all whom it'may concern:

Be it known that I, WARREN S. KESSLER, a

citizen of the United States, residing at Albion, in the county ofCalhoun and State of Michigan, have invented certain new and usefulImprovements in Automobile Lifting- Trucks, and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. Y

My present invention is an automobile lifting-truck; and it consists ofa truck provided with a motor so connected as to propel it from place toplace, lifting arms or platform, and a device for lifting and holdingthe-said arms or platform at the required height.

In the accompanying drawings I have shown one form in which I havecontemplated embodying my invention, and my said invention is disclosedin the following description and claims.

In the said drawings, Figure 1 is a view in side elevation of one of myimproved trucks, and Fig. 2 is a View from the opposite side.

In the said drawings, A is the main supporting-frame of the machine.This main frame is supported at its forward end on the axle B of twotruck-wheels b 6, the wheels being rigidly secured to the axle. of theframe is supported on two caster-wheels c 0. On each side of the frame Aare mounted two vertical bearings c c, in one of which is journaled therod or shaft O. The lower end of this rod or shaft is bifurcated, andbetween the two arms of the bifurcated part is one of the caster-wheels0. The upper end of the rod or shaft O is provided with the crank-arm 0by which the wheel 0, connected with the shaft or rod, can be turned inany direction. On the .opposite side of the machine is a similar bearingin which there is mounted a similar shaft or rod O, which extends but ashort .distance above the bearing 0, and its lower end is in like mannerbifurcated and has r0- tatably mounted therein the other caster-wheel c.To each of the bifurcated castervwheel The rear end supports is rigidlysecured a forwardly-extending arm 0 c and these two arms are connectedby the link 0*, so that the caster-wheels move in unison.

The motor D, which in this instance is a steam-engine, is mounted uponthe main frame near the rear end of the same. Upon the engine-shaft d ismounted a spur gear-wheel d. This gear-wheel meshes with a gear-wheel ona counter-shaft e, mounted in the frame below the engine. On shaft e isplaced the small sprocket-Wheel e", and a sprocket-chain E connects thissprocket with a large sprocket b on the axle B.

The engine is preferably provided with'reverse mechanism, by the aid ofwhich the truck can be moved in either direction.

Tothe main frame, a short distance to the rear of the center of thesame, are secured at each side depending brackets F, and to thesebrackets are pivoted the lifting-bars F. These bars extend forwardlybeyond the front end of'the main frame, preferably passing through slotsin brackets Gr, secured to the front end of the main frame and over ashaft Gr, mounted in said brackets G. The shaft G is provided beneaththe bars F with crank-arms or cams g.

To the center of the shaft Or" is rigidly secured the arm g. To theupper end of the arm g is secured a flexible connection 9 such as achain or like article, which passes beneath and partially around thepulley h, secured beneath the frame, and then upward to the liftingdevice H. This lifting device is shown as being in this instance asteam-lift, and the chain or flexible connection g is securedxto thepiston-rod of the steam-lift. To the outer endsof the lifting-bars F issecured a cross-head I, and from this cross-head projects the short armsor platform 2'.

r J is the steam-boiler, and K is the watertank, both of which aremounted'upon the main frame, as shown.

L is the seat for the operator, and this is supported in any preferredway from the main frame. It is shown in this instance as being supportedby the U-shaped bar or bars Z, which at their lowest point carry afootboard Z for the feet.

The truck here illustrated was designed for handling annealing-pots usedin the manufacture of malleable iron, and the operation will -be readilyunderstood. The annealing-pots used in the manufacture referred to aresupported upon bases, having downwardly-extending webs which rest on theflooring. The operator causes the truck to move forward and thrust thearms 2' under the base, upon which one or more annealing-pots have beenplaced. The lift is then operated in this instance by admitting steam tothe lower end of the cylinder and the rear end of the chain or flexibleconnection 9 drawn upward. This draws the upper end of the arm 9backward, causing the cams g to raise the lifting-bars with the potsupon the arms 2'. The truck then is operated to carry the pots to thepoint desired, when the steam in the lifting-cylinder is allowed toescape slowly and the load is deposited.

Vhile I have shown this truck as constructed for certain use, it may beconstructed for other uses and adapted to lift its load such greaterdistances as may be desired, and the various parts may be modified toadapt the use for which it is intended.

What I claim, and desire to secure by Letters Patent, is-

1. An automobile-truck provided with lifting-bars having alifting-platform rigidly secured thereto and means for raising andlowering said lifting arms and platform, substantially as described.

2. In an automobile-truck, the combination WARREN S. KESSLER. Witnesses:
